A color-tunable pillarene coordination polymer (DCP5-Eu1Tb3) with attractive white-light emission properties and capable of nitroaromatic pollutant detection in biological platforms was constructed.
Synthesis of a new functionalized pillar[4]arene[1]quinone and its host–guest complexation with a bis-imidazolium dication was demonstrated. 1D/2D NMR spectroscopic analyses and high-resolution mass spectrometric analyses showed the formation of the pseudo[3]rotaxaneassembly upon host–guest complexation. 1H NMR titration experiments revealed the role of hydrogen bonding motifs in bringing positive
证明了一种新的功能化支柱[4]芳烃[1]醌的合成及其与双咪唑鎓离子的主客体络合。1D / 2D NMR光谱分析和高分辨率质谱分析表明,主体-客体络合后会形成假[3]轮烷组装体。1 H NMR滴定实验通过比较柱[4]亚芳基[1]醌与双咪唑基宾的主体-客体络合的结合常数,揭示了氢键基序在带来正协同作用中的作用。还证明了假[3]轮烷装配的阴离子响应性。
Pillar[5]arene based conjugated macrocycle polymers with unique photocatalytic selectivity
huge challenge in photocatalysis. Reported herein is a host-guest interaction strategy to endow photocatalysts with special selectivity. By adjusting the precursors, conjugated macrocycle polymers (CMPs) with pillar[5]arene struts (CMP-1 and CMP-2 ) and a corresponding non-pillar[5]arene-contained conjugated organic polymer (COP-1) were prepared and the photocatalytic activities toward sulfide derivatives

Despite the fact that the rim and lateral functionalizations of pillar[n]arenes have been well explored, ortho-functionalization has rarely been realized. In this work, we report a facile method of introducing a single functionality ortho to the hydroxyl group in A1/A2-dihydroxypillar[5]arene via a Grignard addition to pillar[4]arene[1]quinone followed by a dienone–phenol rearrangement. The described

ring opening of pillar[4]arene[1]quinone 1. And the Prato reaction of 2 with [60]fullerene led to [60]fullerene bisadducts, from which trans-4 cyclic regioisomer 3 was isolated and characterized. The fulleropillar[4]arene 3 showed a larger cavity and can accommodate a viologen derivative C12V2+ with a much stronger affinity than permethyl pillar[5]arene (MP5) and pillar[4]arene[1]quinone 1.
